Documentation: Drop install directive for Doxyfile

Building the documentation reports warnings,

WARNING: Project targetting '>= 0.40' but tried to use feature introduced in '0.50.0': install arg in configure_file
WARNING: Project specifies a minimum meson_version '>= 0.40' but uses features which were added in newer versions:
 * 0.50.0: {'install arg in configure_file'}

Due to the usage of the directive configure_file { install: false } in
Documentation/meason.build which is introduced in meson 0.50. As we do
not wish to install the Doxyfile no install_dir is set so there is no
need to explicitly state that it should not be installed. Silence the
warning by dropping the install directive.
